SAW=CATCHER FQR BAND-SAW MILLS.

SPECIFICATION forming part of Letters Patent No. 356,220, dated January 18, 1887.

Application filed April 22, 1886. Serial No. 199,762.

To all whom it may concern.-

Be it known that I, GUSTAVUS H. ZSOHEOH, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Saw-Catchers for Band- Saw Mills; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to a saw-catcher for a band sawing-machine, the object thereof being to provide a device for catching the saw when,

cause, it is thrown from the saw-wheel while in motion; and the invention consists in the. construction, arrangement, and combination of parts, as will be hereinafter fully set forth. In the annexed drawings, illustrating my invention, Figure 1 is a front elevation of my improved device for catching saws, and shows also the rim of the saw-wheel. Fig. 2 is an end elevation of the same. Fig. 3 is a top plan view, and Fig. 4. is a detail crosssection, of the saw-catcher through one of its rollers.

Like letters of reference designate like parts in the several figures.

B represents the upper band-saw wheel, which is suitably journaledin the frame, one end of itsjournal or shaft entering the column A, while the other end is upheld by the outhangingjournal-box arm G. A semicircular rim, (3, somewhat less in diameter than that of the band-wheel and provided with a radial series of spokes, D, secured to said rim, and

also to a central hub, E, is situated in close proximity to the band-wheel. The center of the hub E of this semicircular wheel is firmly secured to the journatbox arm G by screws or bolts, and the rim 0 is concentric with the band-wheel, and is preferably made of flat bar-iron bent into the required shape.

The rim 0 of the saw-catching device is provided on its outer surface with a series of transverse rollers, F, mounted each in a stand,

(No model.)

a, which is made fast to the rim 0 by rivets 50 or other suitable means. These stands a are also so constructed as to have journaledtherein not only the horizontal roller F, but a second roller, H, situated at right angles to the roller F. There may be any number of these roller 5 5 devices situatedagreater orless distance apart throughout the length of the semicircular rim, and when it is so desired the construction may be so modified as to dispense with the secondary rollers H, and provide in lieu thereof a 5g flange, I), (see Fig. 4,) which will likewise be perpendicular to the roller F, and which may be made in sections-that is, one partfor each roller, and none in the intervening space between the rollers; or the flange b may be a 6 continuous semicircular strip secured to each stand (1. These rollers are preferably made of wood and furnished with iron gndgeons, which are fitted into suitablejournal-holes in the stands a a.

It will be evident from the foregoing description of the construction of the parts how the device will operate in actual practice. The inner extremities of the rollers F are located close to the band-saw. WVhen, there- 7 fore, the saw, during its revolution at a high rate of speed, happens from any cause to be thrown from the wheel, it will be caught by the rollers F, upon which it will continue its revolving motion,without any violent or sud- 8o den resistance, until at length the frictional contact with the rollers causes it to stop. The stoppage of the saw is gradual, therefore. Were the saw to be thrown upon a dead surface, there would be such a suddenresistance 8 5 verse rollers journaled in suitable stands upon the rim, substantially as shown, and for the purpose set forth.

2. A saw-catcher for band'saw mills, consisting of a semicircular rim located close to the upper band-saw wheel and a series of roller devices secured at intervals upon the rim, each of said devices consisting of a stand, in which is jonrnaled a roller transverse to the rim, and a second roller at right angles to the first, substantially as shown and described.

3. A saw cateher for bandsaw mills, consisting of a semicircular rim located close to and concentric with the upper bandsaw wheel, aseries of transverse rollers j ourn aled in stands upon the rim, and a series of rollers or guards perpendicular to those of the first series, substantiall y as described.

4. In a saw-catcher for band-saws, the combination of the rim 0, spokes D, and hub E, rigidly mounted upon a support, and a series of rollers, F, jonrnaled in stands a, secured to the rim, as specified and shown.

5. The combination of the rim 0, the stands a, secured thereto, the rollers F, journaled in the stands and transverse to the rim, and the rollers or guards H, likewisejournaled in the stands a, and at right angles to the rollers F, all arranged substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
